Occasionally won't crank. Does a JK have one of those dodgy ignition actuators?
I've got a 2010 Wrangler Sport.
2 months ago I noticed that sometimes when I went to start the car, nothing would happen. No clicking, no cranking. But ignition lights on, indicators worked etc. I would try again and then presto, it would start immediately. Happened only a couple of times and since it was winter and I wasn't using it, I sort of ignored it...
The problem got worse. This morning it wouldn't start after three attempts. First I checked the battery. 10.75V. Suspicious. Original battery. But maybe something was draining it. So I put the jumpers on the other car and it started immediately. Ran it for 30 minutes. Stopped the engine. Battery read 12.7V. Tried to start it. Nothing. But still had ignition lights. Checked the voltage. 10.7V. Suspected bad battery.
Jumped the care and went to the store to replace it. New battery installed. 12.7V. Went to start it. Fired up straight away. Went inside and paid. Came outside. Wouldn't start! Tried 3 times. Went inside to ask the guy for a jump. Came outside. Started up! The guy had one of those looks on his face like 'Surrre.' Went home.
If you try to start it 4 times, it might fire up perfectly twice, then the other two times not at all. Sounds like a connection problem.
I've read a lot on this and plenty of people seem to have had problems with the ignition actuator pin breaking off, a $30-40 Dorman part. But this seems to be for '07 and older jeeps. I don't see this part listed for a JK.
Does a JK use this part or something else? I haven't seen any posts for problems like this on a JK.
